Beyond simple coding skills, this lecture is like a roadmap that teaches 'how' to think and grow as a developer. I was able to build a solid foundation with the history and philosophy of the web, and learn how to maximize productivity using Cursor, the latest AI development tool. Projects that gradually increased in difficulty, from a portfolio to an exchange rate converter using API, allowed me to effectively internalize what I learned, making the learning process more effective. In particular, the various segments filled with the instructor's deep expertise provided the best mentoring, prompting contemplation of growth beyond technical skills. This is truly a perfect lecture for developers in the AI era.
